Windows Print Spooler Components: Information disclosure of credentials
Summary
Insufficiently protected credentials in Windows Print Spooler Components allow an authorized local attacker to disclose information. The attacker needs local access and a low-privilege account, and the CVSS vector indicates high attack complexity and impact on confidentiality only. The CVE is awaiting NVD analysis, and no exploitation or public proof of concept has been reported.

Workaround
Unknown.
- No Microsoft workaround identified. Install the November 2026 security update on all affected builds.
Exploitation
- No exploitation in the wild known.
- No public proof of concept found.
- CISA SSVC: exploitation none, automatable no, technical impact partial.
Our recommendation
- Deploy the November 2026 cumulative update to all affected Windows clients and servers, prioritising servers and domain controllers.
- Disable the Print Spooler on systems that do not need printing.
- Verify installed build numbers against the Microsoft Security Update Guide after patching.
- Review whether printer or service accounts are used on affected hosts, as the CWE concerns credential exposure.
- Monitor for a public proof of concept and check CISA KEV and NVD once the CVE is analysed.
